A new 2D Prince of Persia is in development using Rayman Legends' UbiArt Framework engine, according to a report posted by French website Le Portail du Jeu Video.
The site claims to have been told that the game will use "the same techniques of animation [as used] in the last Rayman" and see the Prince's body "divided into several parts (torso, pelvis, leg, shin, foot, forearm, hands, etc..) that can be animated independently of each other.
"This provides a real diversity / credibility in the postures and movements of the hero...," the site says. "The quality of the work is to believe [it is] 3D modelling [with] transitions [that are] are fluid and feel well made."
Ubisoft has yet to announce a new title in the Prince of Persia series, but it has begun using its UbiArt engine for projects besides Rayman. This month's platform-RPG Child of Light also uses UbiArt Framework, for example.
Ubisoft told VideoGamer.com that it "does not comment on rumours or speculation" when contacted about the report earlier today.
